Thanks George,
 I agree with any queen ,if she has any pheromones.
 The breeder told me that they have tried the queens on emerging brood in a
cage and that did not work.
 I will be trying one out with all the tricks I can think of, for a problem
introduction.
 I will use a little QMP ( mandibular gland pheromone ) if just nurse bee's
will not solve the problem.
